This invention relates to convertible furniture and is more particularlydirected to a double sofa that is convertible to twin beds.

A principal object of the present invention is to provide a double sofathat is readily and with little effort converted for use as twin beds bya simple swinging movement of the sofas and as readily restored to useas a double sofa by a similar but reverse swinging movement thereof.

Another object of the present invention is to provide twin bed and sofacombination with two pairs of links pivotally mounted to a support framefor guiding the movement of the bed frames from a double sofa positionto their twin bed position and vice versa.

A still further object of the present invention is toprovide acombination twin bed and sofa with simple locking devices for releasablysecuring the bed frames in either the sofa position or in the twin bedposition.

A still further object of the present invention is to provide acombination twin bed and sofa which is readily swung from its sofaposition to twin bed position having a linkage system and roller typefloor engaging casters for supporting the bed frames thereby obviatingthe necessity for a track system for guiding the casters.

With these and other objects in View, the invention will be bestunderstood from a consideration of the following detailed descriptiontaken in connection with the accompanying drawings forming a part ofthis specification, with the understanding, however, that the inventionis not confined to any strict conformity with the showing of thedrawings but may be changed or modified so long as such changes ormodifications mark no material departure from the salient features ofthe invention as expressed in the appended claims.

In the drawing:

FIGURE 1 is a perspective view of my combination twin bed and sofashowing the arrangement of the mattress frames when in use as a sofa.

FIGURE 2 is a similar view showing the mattress frames having taken theposition when used as twin beds.

FIGURE 3 is a perspective view of the support frame and mattress framesshowing one mattress frame locked in its sof-a position and the othermattress frame locked in its twin bed position.

FIGURE 4 is a fragmentary top plan view of the frame structure shown inFIGURE 3 with one mattress frame having been swung and being shown inits sofa position, intermediate position and twin bed position.

FIGURE 5 is a detailed cross sectional view taken along the line 55 ofFIGURE 4.

Referring to the drawings wherein like numerals are used to designatesimilar parts throughout the several views there is shown by way ofilllustration my combination twin bed and sofa 10, along which in anelevated position is mounted a conventional bolster 11. The bolster 11which is supported on a support 12 by brackets (not shown) secured toupright members 13 is so positioned that it lies over the beds 10, 10when the latter are positioned for daytime use as a double sofa as shownby FIGURE 1.

The upright members .13 have their lower ends welded or otherwisesecured to a base member 14 with outwardly extending foot portions 15and 16 for supporting the upright members 13 and the bolsters 11 in astable position. Each of the foot portions 16 also serves as a pivotsupport for a link 17 having one end pivoted as at 18 to the end of thefoot portion 16 while the other end of the link 17 is pivoted by a pivotpin 19 to a cross bar 2 of a mattress frame 21.

The mattress frame 21 of the sofa bed 10 is of conventional constructionconsisting of angle members 22 and 23 welded at their ends to form asubstantially rectangular support for an inner spring and mattressandthe cross bar 20 welded at its ends to the angle members 22 inparallel and spaced relation with the end angle member 23 which formsthe head of the bed 10.

At three of the corners of the mattress frame 21 are cross braces 24having floor engaging roller casters 25 pivotally secured thereto. Inorder to permit the swinging of the bed 10 without interfering with thefoot portion 16, a fourth floor engaging roller caster 26 is pivotalllysecured to a corner brace 27 extending between the angle member 22 andcross bar 20.

Means are provided to compel the mattress frame 21 to swing in a desiredpath whereby the frames 21 move from a position alongside the support 12as shown by FIGURE 1 to a position substantially perpendicular with thesupport 12 as shown by FIGURE 2. This means consists of a link 27 whichis pivotally secured at one end to the base member 14 as at 28 while theother end is pivoted by a pivot pin 29 to the angle member 23 formingthe head of the mattress frame 21.

With the construction of the linkage system 17, 27 as shown anddescribed herein the sofa beds 10, 10 are readily and with very littleeffort rolled on the casters 25 and 26 from the sitting position asshown by FIGURE 1 to the sleeping position as shown by FIGURE 2. This isaccomplished by exerting a slight pulling force on the foot of the sofabeds 10 to cause the foot of the sofa beds 10 to swing in a sweeping areas best illustrated in FIGURE 4. Position A of the mattress frame 21 asshown by solid lines is the position of the sofa bed 10 for sittingpurposes. As the foot of the sofa beds 10, in other words the outer endsof the mattress frame 21 are pulled away from the bolsters 11 or thesupport 112, the link .27 pivots about the pivot pin 28 as the pivot pin29 at the other end of the link 27 describes an are indicated by theletter a. At the same time the link 17 pivots about the pivot pin 18 asthe pivot pin 19 at the other end of the link 17 describes an areindicated by the letter 11. The foot of mattress frame 21 will swingoutwardly as shown to position B at which time the pivot pins 28, 29 and'19 will be substantially in a straight line. A further swingingmovement of the foot of the mattress frame 21 will now cause the pivotpin 29 to continue to pivot about the pivot pin 28 and the pivot pin 29will describe the arc c which is a continuation of are a while the pivotpin 19 will now reverse its swinging movement and now swing back alongthe same arc b until the mattress frame 21 has arrived at position Cwhich is for sleeping purposes. In this position the sofa beds 10, 10will be llying alongside each other lengthwise in close proximity toeach other as shown by FIGURE 2 with the head of the sofa bed '10removed from the support 12 so that the bolster-s 11 do not now lie overthe sofa beds 10.

To return the sofa beds 10 to their original position for sittingpurposes, a slight push on the foot of the sofa beds 10 in the directionof outer ends of the support 12, the sofa beds will commence to roll onthe casters 25 and 26 moving fromposition C toward position B at whichtime pivot pin 29 is swinging in are c and pivot pin 19 is swinging in adirection away from the support 12 in the arc b. Again, when the sofabed 10 has arrived at position B the pivot pins 28, 29 and 19 will bepositioned in a straight line after which continued swinging movement ofthe sofa bed 10* will cause the pivot pin 29 to swing in the are a andthe pivot pin -19 to swing in a di- 3 rection toward the support 12 inthe same are b until position A has been assumed by the sofa bed Inorder to releasably lock the sofa beds 10 in position at positions A,and C, identical locking members 3-0 and 31 are provided. Lockingmembers 39* which are welded to the end portions of the base member 14consists of substantially S-shaped portion having a cam surface 3 2 anda cradle portion 33, the cam surface 32 being positioned at a higherlevel than the cradle portion 33'. When the sofa beds 10 are swung totheir position for sitting purposes, namely position A the angle member22 of the mattress frame 21 adjacent to the support 12 will engage thelocking member 30, slide over the cam surface 32 and come to rest withinthe cradle portion 33. The sofa bed 10 will remain in position A untilit is desired to swing the sofa bed 10 to the sleeping position C whenthe frame 21 is lifted from within the cradle 33 and the mattress frame21 swung away from the support 12.

The locking members 31 which secure the sofa beds 10 when in position Care mounted on a cross member 35 whose ends are welded or otherwisesecured to the foot portions 16. The locking members 31 being identicalin construction with the locking members 30 will engage theangle members23 furthest from the support 12 when the sofa beds 10 have arrived atthe position C and lock same at the sleeping position.

When the two sofa beds 10 are in their positions for sleeping purposes,the beds 10 will be positioned in close proximity to each other. Thisdistance between the sofa bed 10 may be varied as desired by providingdifferent length links 17, 27.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. A combination twin bed and sofa comprising an elongated supportmember, a plurality of foot portions secured to said elongated supportmember, a pair of bed frames positioned end to end in substantiallyparallel relation and in close proximity with said support member and inclose proximity to each other, a plurality of floor engaging rollermeans supporting said bed frames, a pair of said foot portions extendingat an obtuse angle from said support member to proximity of one end ofsaid bed frames, each of said last named foot portions terminatingbeneath said bed frames, a link pivotally mounted at one end to each ofsaid last named foot portions and at the other end to each of said bedframes in proximity of said one end of said bed frames, a pair of secondlinks, pivot means mounting one end of said second links to saidelongated support member and the other end to said one end of each ofsaid bed frames whereby upon the swinging of the other end of said bedframes, said links will pivot-ally guide said bed frames to a positionsubstantially parallel to each other and normal with and in closelyspaced relation to said elongated support member.
